DLS-240-45

240VAC - 12VDC CHARGER/CONVERTER

DESCRIPTION

The DLS-240-45 battery charger/power converter from IOTA Engineering converts nominal 240V A.C. voltage to 13.4V D.C. As a power supply, its tightly controlled regulation allows the user to operate any appropriate nominal D.C. load up to the converter’s rated output current. As a battery charger, the DLS-240-45 will maintain the battery, delivering its full-rated current when the battery capacity falls sufficiently low. The voltage is set to deliver its maximum current for the necessary period of time that minimizes undue stress to the battery caused by heating of its cells. This helps to ensure the longest possible life of the battery. Over time, as the battery nears its full capacity, the converter will float-charge the battery to prevent self-discharge of its cells.

MODELS

DLS-240-45/IQ4 (with integrated IQ Smart Charger)

INSTALLATION OVERVIEW

Disconnect the positive side of the battery before installation. Connect the positive

(red) and negative (black) terminal lugs to battery or load. Always use the proper size wire based on the amperage of the converter and the battery. When connecting to a battery, a breaker should be installed within 18 ″ of the battery, connecting the battery positive to the line side of the breaker, and the DLS to the load side. Connect

“Chassis Bonding Lug” on the DLS to vehicle chassis or other grounding source.

The DLS-240-45 is equipped with a three-prong A.C. input cord for connection to the 240VAC power source. The cord is rated 250VAC, and is 3 feet long from the input side of the unit. See chart for maximum current draw and required input voltages. For complete installation guidelines, refer to the installation manual.

DUAL VOLTAGE JACK

The DLS-240-45 is equipped with a Dual Voltage Jack and Dual

Voltage Plug that allows manual switching from a long-term float voltage of 13.6vdc to 14.2vdc. When the Dual Voltage Plug is inserted in the jack, the voltage increases to 14.2vdc for occasional fast charging. When the plug is removed, the voltage drops to

13.6vdc to reduce battery water loss.

The Dual Voltage Jack also allows for easy installation of an external IQ4 Smart Charger for automatic 3-stage charging

(optional).

If the unit is equipped with an internal IQ4 smart charger, two-step charging is not needed and the Dual Voltage

Jack is disabled. For details on 3-stage charging voltages, refer to the IQ4 instruction manual.

DUAL VOLTAGE PLUG

WARRANTY

The DLS Series Battery Charger/Power Converter is warranted from defects in materials or workmanship for two years from date of retail purchase, and limits the remedies to repair or replacement. This warranty is valid only in the continental United

States and Canada. For complete warranty details, contact Customer Service or visit www.iotaengineering.com.
